You can use session to reset the password.
The bakend
public IActionResult ForgetPassword()
{
//email: send a random code and save it in a session
HttpContext.Session.SetString("randomcode",new Random().Next(1000,10000).ToString());
return View();
}
[HttpPost]
public IActionResult ForgetPassword(string password,string randomCode)
{
//if the Vertification Code is not equals to the randomcode, return fail
if (randomCode != HttpContext.Session.GetString("randomcode"))
{
return View();
}
//update database
return View("index");
}
Give the new password in this form.
<form action="/home/ForgetPassword" method="post">
Password :<input type="text" name="password" value="" />
Confirm Password :<input type="text" name="confirm_password" value="" />
Vertification Code: <input type="text" name="randomCode" value="" />
<input type="submit" name="reset" value="reset"
onclick="Confirm(event)"/>
</form>
javascript
<script>
function Confirm(e) {
var passw = document.getElementsByName('password')[0].value
var confirmPassw = document.getElementsByName('confirm_password')[0].value
if (passw != confirmPassw)
e.preventDefault()
}
</script>
